我有下面的php代码示例，用于从带有“in”的数据库中选择数据condition:-
产品型号.php

public function product_attribute_filter($data) {
            $sql = "select p.name,p.image from product p where  p.condition in (?)"; 

            $result = $this->db->query($sql, array($data['condition']));
            $records = array();
            foreach( $result->result_array() as $r ) {

            }
            return $records;
        }

产品.php

public function product_attribute_filter() {

        $this->load->helper('my_check');
        $data = checkPostKey(array('condition'));
        $result = $this->Product_category_model->product_attribute_filter($data);
        if (count($result) == 0) {
            echo json_encode($result,JSON_UNESCAPED_SLASHES);
        } else {
            echo json_encode($result,JSON_UNESCAPED_SLASHES);
        }
    }

我怎样才能把它贴成 select p.name,p.image from product p where p.condition in ('New','Used') ??
还有，我怎样才能叫 Postman 来？目前这不起作用。请帮忙。谢谢

我根据scuzzy示例代码及其工作更改了以下代码。

$array = array("New","Used");

                $placeholder = '"' . implode('", "', array_values($array)) . '"';

                $sql = "select p.name,p.image from product p where  p.condition in (" . $placeholder . ")";
